DETAILED DESCRIPTION

Example embodiments will now be described more fully with reference to the accompanying drawings.

Referring initially to FIG. 1, exemplary embodiments of a trampoline 10 are illustrated. As shown, the trampoline 10 can generally include a frame 12, a jumping mat assembly 14, an enclosure system 16, one or more sensors 18 a-18 h, and a feedback system 20. As will be discussed in greater detail, the sensor(s) 18 a-18 h can detect activity, status, etc. of one or more users 21 on the jumping mat 14, and the feedback system 20 can provide one or more feedback signals (e.g., sound, visual signals, tactile signals, etc.) in response to the detected activity, status, etc. As such, the feedback system 20 can provide a variety of information to the user(s) 21.

In some embodiments, the sensors 18 a-18 h and feedback system 20 of the trampoline 10 can detect and/or provide information regarding: 1) the location of the user 21 relative to the jumping mat assembly 14; 2) whether the user 21 has completed a predetermined movement relative to the jumping mat assembly 14; and/or 3) the number of the users 21 that are bouncing or otherwise located atop the jumping mat assembly 14. Additionally, the sensors 18 a-18 h and feedback system 20 of the trampoline 10 can detect and/or provide information when: 1) the user 21 impacts the enclosure system 16; 2) the user 21 is within a predetermined distance of a peripheral edge 22 of the jumping mat assembly 14 (e.g., to act as a warning for the user 21); and/or 3) the user 21 has completed or travelled a “lap” around the jumping mat assembly 14. Thus, the sensors 18 a-18 h and feedback system 20 of the trampoline can greatly enhance the experience of using the trampoline 10.

The features of the trampoline 10 will now be discussed in greater detail. The frame 12 can include a plurality of strong, rigid, elongate poles or other similar structures. For instance, the frame 12 can include steel or aluminum poles that are removably attached together. The frame 12 can include vertically extending legs, horizontally extending members that extend between the legs, and the like.

Moreover, the jumping mat 14 can be a relatively thin, flexible, woven material that is strong enough to support users that bounce thereon. The jumping mat 14 can include a peripheral edge 22. The edge 22 can be rounded (e.g., circular), polygonal (e.g., rectangular, square, etc.), or the edge 22 can have any other shape.

A plurality of springs (not shown) or other resilient members can operably couple the mat 14 to the frame 12. The springs can be evenly spaced about the edge 22. One end of each spring can be attached to the edge 22, and the opposite end of each spring can be attached to the horizontal members of the frame 12. Accordingly, when the user 21 bounces on the mat 14 and deflects the mat 14 downward, the springs can resiliently deflect and then recoil. As such, the user 21 can be repeatedly propelled into the air from the mat 14.

The enclosure system 16 can include one or more vertical supports 24 (e.g., poles) that are connected to the frame 12 and that extend upward from the frame 12. The vertical supports 24 can be substantially rigid, or the vertical supports 24 can be somewhat resilient. The enclosure system 16 can also include a wall member 26. The wall member 26 can be a thin, flexible sheet of material that is connected to the top ends of the vertical supports 24 and that is connected to the frame 12 and/or the edge 22 of the mat 14 to thereby enclose the jumping mat 14. In some embodiments, the wall member 26 includes netting or other similar material. During use, the enclosure system 16 can maintain the user 21 on the jumping mat 14. For instance, if the user 21 bounces laterally off of the mat 14 toward the wall member 26, the wall member 26 can limit lateral movement of the user 21 such that gravity directs the user 21 back toward the mat 14.

The sensors 18 a-18 h can be of any suitable type, and the sensors 18 a-18 h can be used for detecting a variety of conditions related to the one or more users 21 on the mat 14. For instance, one or more of the sensors 18 a-18 h can include a transducer that transforms mechanical energy associated with the bouncing of the user to a corresponding electrical signal, and the electrical signal can be used by the feedback system 20 for purposes that will be discussed below.

At least one of the sensors 18 a-18 h can include a commercially-available accelerometer, proximity sensor, camera, motion detector, piezoelectric sensor, or other type. Also, the trampoline 10 can include any suitable number of sensors 18 a-18 h, and the sensors 18 a-18 h can be disposed in any suitable location.

For instance, the sensors 18 a, 18 b, 18 c, and 18 d (i.e., mat sensors) can be operably coupled to the jumping mat 14. As shown in FIG. 1, for example, the sensors 18 a, 18 b, 18 c, 18 d can be evenly spaced from each other (e.g., separated by ninety degrees adjacent the edge 22 of the mat 14). Also, in some embodiments, the sensors 18 e, 18 f (i.e., first enclosure sensors) can be coupled to the wall member 26 of the enclosure system 16, and the sensors 18 g, 18 h (i.e., second enclosure sensors) can be coupled to the vertical supports 24 of the enclosure system 16. The sensors 18 e, 18 f, 18 g, 18 h can be evenly spaced from each other (e.g., separated by ninety degrees about the enclosure system 16). Similar sensors can also be attached to the frame 12.

The sensors 18 a-18 h can be used to detect various conditions (i.e., bouncing conditions) related to the user(s) 21 on the mat 14. More specifically, each sensor 18 a-18 h can be triggered to output a signal (e.g., an electric signal) when a load (i.e., a bouncing load) is applied to the mat 14 and/or the enclosure system 16. In some embodiments, the sensors 18 a-18 h can be triggered only if the bouncing load exceeds a predetermined threshold. Furthermore, the sensors 18 a-18 h can be triggered if displaced from a neutral position beyond a predetermined distance (vertically and/or laterally). Also, because the bouncing loads can be substantially localized, the sensitivity of the sensors 18 a-18 h can be adjusted such that only those sensors 18 a-18 h adjacent the applied load are triggered. As such, the location or other status of the user 21 can be detected by the sensors 18 a-18 h.

Furthermore, in some embodiments, a single bouncing load of the user 21 (e.g., impact of the user 21 with the mat 14 and/or displacement of the mat 14) can trigger multiple sensors 18 a-18 h (at least two sensors 18 a-18 h) simultaneously. Also, in some embodiments, two or more sensors 18 a-18 h can output different signals, depending on the spatial relationship between the bouncing load and the particular sensor 18 a-18 h. For instance, a sensor 18 a-18 h directly adjacent the applied bouncing load can output a stronger signal than another sensor 18 a-18 h that is remote from the applied load. The signals can differ from each other by output signal voltage, current, frequency, wavelength, etc. based on the location of the particular sensor 18 a-18 h relative to the applied load. Thus, the different signals from the multiple sensors 18 a-18 h can be compared to thereby detect the location, movement, or other status or condition of the user(s) 21 as will be discussed.

The feedback system 20 can further include a controller 28. The controller 28 can be a computerized device having a processor 30, a memory device 32, and other computerized hardware. In some embodiments, the controller 28 can include a communications system that can communicate (e.g., wirelessly) with the Internet or other computerized network. The memory device 32 can include Random Access Memory (RAM) and/or Read Only Memory (ROM) and can store various software, programmed logic, and the like. The controller 28 can be in operable communication with the sensors 18 a-18 h.

The controller 28 can also include a power source 34 that supplies electricity thereto. The power source 34 can include one or more batteries. Also, in some embodiments, the controller 28 can include a power cord for electrically connecting to a conventional power outlet.

The controller 28 can additionally include an ON/OFF switch 36. The switch 36 can be a manual switch with which the user can manually turn the power supply from the power source 34 ON and OFF. Also, in some embodiments, the switch 36 can be an automatic switch that automatically turns the power supply ON and OFF. For instance, if the sensors 18 a-18 h do not detect any jumping activity for a predetermined amount of time (e.g., five minutes), the switch 36 can automatically switch the power supply OFF.

In some embodiments, the controller 28 can also include an input device 37 with which the user can provide input. For instance, the input device 37 can include a keypad, keyboard, knobs, control dials, etc. The input device 37 can also be used for selecting among different programs loaded on the controller 28, which will be discussed in greater detail below.

The feedback system 20 can also include one or more feedback devices 38 a, 38 b. There can be any number of feedback devices 38 a, 38 b, and the feedback device(s) 38 a, 38 b can be of any suitable type. For instance, the feedback system 20 can include an audible transducer, such as a speaker 40 that emits a sound in response to electrical signals from the sensors 18 a-18 h. The speaker 40 can output a beep, speech, or any other suitable sound. The feedback system 20 can also include a visual transducer, such as one or more lights 42 (e.g., light emitting diodes or LEDs, etc.), that emit a light in response to electrical signals from the sensors 18 a-18 h. Also, the light(s) 42 can emit a variety of colors, depending on the signals sent from the sensors 18 a-8 h. The feedback devices 38 a, 38 b can also include a display (e.g., a computer screen) providing more detailed visual information. The system 20 can also include other types of feedback devices 38 a, 38 b, such as tactile feedback devices (not shown) that selectively vibrate or provide another type of tactile feedback or olfactory feedback devices that selectively emit an odor.

The feedback devices 38 a, 38 b can be disposed in any suitable location relative to the frame 12. For instance, one or more of the feedback devices 38 b can be attached to or directly adjacent the frame 12, the mat 14, and/or the enclosure system 16 such that the users 21 bouncing on the mat 14 can see, hear or otherwise receive the feedback signals from the devices 38 b. In the embodiments illustrated in FIG. 1, for example, the feedback device 38 b is fixedly attached to the underside of the mat 14 and is substantially centered on the mat 14. Also, as shown in the embodiments of FIG. 1, the feedback device 38 a can be remote from the frame 12, the mat 14, and the enclosure system 16. For example, the feedback devices 38 a can be located inside a house while the frame 12, mat 14, and enclosure system 16 are located outside the house, and as such, parents or other occupants within the house can see/hear the feedback signals for remotely monitoring bouncing activity on the mat 14. Although only the feedback device 38 a is shown as including both a light 42 and a speaker 40, it will be appreciated that the feedback device 38 b can also include a light 42, a speaker 40, and/or a feedback device for providing another type of feedback signal.

In use, the sensors 18 a-18 h and feedback system 20 can act as a safety system or alarm. For instance, in some embodiments, the system 20 can be activated to emit feedback signals if the sensors 18 a-18 h detect any bouncing on the mat 14. Accordingly, the system 20 can assist parents in making sure that no kids are bouncing on the mat 14 without supervision.

Also, during normal bouncing, the system 20 can be used for notification that someone has bounced too close to the edge 22 of the mat 14. For instance, in some embodiments, the processor 30 can compare the signal strength of the signals sent from each of the sensors 18 a-18 h. In some embodiments, the sensors 18 a-18 d distributed about the edge 22 of the mat 14 are compared. If the difference between the signals from these sensors 18 a-18 d is largely the same (e.g., within a predetermined threshold), then it can be assumed that the user is safely bouncing within the center area of the mat 14, and no feedback signals will be provided by the feedback devices 38. However, if one of signals from one of the sensors 18 a-18 d is substantially stronger than the others, it can be assumed that the user is bouncing too close to the edge 22, and the controller 28 can activate the feedback devices 38 a, 38 b to act as warning alarm.

Furthermore, the processor 30 can compare signal strengths from the sensors 18 a-18 h to ensure that only one user is bouncing on the mat 14 at a time. For instance, if only one user is bouncing, the sensors 18 a-18 h can generate signals at substantially similar signal strengths (i.e., within a predetermined threshold), and no feedback signal will be emitted. However, if multiple users begin bouncing, the signal strengths from the sensors 18 a-18 h are likely to be unbalanced (i.e., one sensor 18 a-18 h is likely to emit a signal that is substantially stronger than the others), and the controller 28 can cause the feedback devices 38 to emit the audible/visual feedback as a result.

Additionally, the system 20 can be used to track bouncing activity. For instance, the sensors 18 a-18 h can track the user's movement about the mat 14. In some embodiments, the user can repeatedly run and bounce about the edge 22 while performing “laps,” and the sensors 18 a-18 h can be triggered in succession during this activity to track the progress of the user 21. The controller 28 can cause the feedback devices 38 to notify the user after each lap has been completed, and/or the memory device can store the number of “laps” that have been completed so that the user can track his or her progress. The feedback devices 38 can also display the corresponding number of calories burned during activity, the amount of time spent bouncing, or other information about the workout. Other exercise routines can also be tracked and/or other movements can be tracked. Moreover, this information can be stored in the memory device 32 such that the user can review past workouts and track workout progress over time.

Still further, the mat 14 can include visible targets, and the sensors 18 a-18 h can be located directly adjacent those targets. Then, the feedback devices 38 can emit feedback signals if the user bounces on and contacts a particular target. The feedback devices 38 can also emit different feedback signals if the user misses the target.

Accordingly, the feedback system 20 can be a useful tool for monitoring bouncing activity on the mat 14. The system 20 can be safer than other trampolines, and the system 20 can also assist the user as an exercise tool.

Referring now to FIGS. 2 and 3, the feedback device 38 b will be discussed according to exemplary embodiments. It will be appreciated that the feedback device 38 a can also include similar features.

As best shown in FIG. 3, the feedback device 38 b can include a housing 50 with a top 52 and a bottom 54. The housing 50 can be platter shaped, and the top 52 and bottom 54 can overlap and attach together to cooperatively house and substantially seal a reflector plate 56 and the light 42 therein. The top 52 and bottom 54 of the housing 50 can be made out of plastic or other weather-proof material.

The reflector plate 56 can be round and can be made out of a mirror-like or reflective material. The reflector plate 56 can also include a number of projections or other surface contours for reflecting light in multiple directions.

Furthermore, the light 42 can include a number of LEDs or other light emitting devices that are arranged annularly atop the reflector plate 56. A wire or other connector can extend from the light 42 and out of the housing 50 to connect to the controller 28. In other embodiments, the light 42 can be wirelessly connected to the controller 28.

The housing 50 can be centered and attached to the underside of the mat 14 by adhesives, fasteners, etc. Also, in some embodiments, the mat 14 can include a pocket (not shown) that receives the housing 50. Accordingly, the light 42 can be readily seen by the user 21 during use.

Also, the speaker 40 of the feedback device 38 b can be operatively connected to the light 42 and/or the controller 28 wirelessly or via a wireless connection. The speaker 40 can be mounted to the frame 12, to the mat 14, to the enclosure system 16, or elsewhere. Thus, the user 21 can readily hear the audible feedback from the speaker 40.

An exemplary sensor 18 a is also illustrated in FIGS. 2 and 3. The other sensors 18 b-18 h can be similar to the sensor 18 a illustrated. The sensor 18 a can be round, flat, and small (e.g., about the size of a penny). Also, the sensor 18 a can be connected to the controller 28 wirelessly or via a wired connection. The sensor 18 a can be fixed to the mat 14 (i.e. fixed directly to the mat 14 only) via adhesives, via fasteners, or any other means. Moreover, in some embodiments, the mat 14 or wall member 26 of the enclosure system 16 can include a pocket that receives the sensor 18 a. In the embodiments shown, displacement of the mat 14 and/or wall member 26 above a predetermined threshold triggers the sensor 18 a.

The sensor 18 a can be a springless type of sensor (e.g., one that does not rely on a biasing member to open and close an electrical switch to detect jumping on the trampoline 10, etc.). The sensor 18 a could include an accelerometer (e.g., a sensor with a suspended mass that is displaced when users 21 jump on the mat 14 to trigger a signal). The sensor 18 a can also be a piezoelectric sensor or other type of transducer. The sensor 18 a can also be a motion detector that emits a beam of infrared or other light, and when the light beam is broken by the presence of a user 21, the sensor 18 a can transmit a corresponding electric signal. The sensor 18 a can also rely on a camera to visually detect users 21. The sensor 18 a can further include an acoustic sensor that detects sounds from users 21 to detect their presence. Moreover, the sensor 18 a can be an occupancy sensor that is integrated with a timing device such that when motion has stopped for a predetermined amount of time, a light extinguishing signal is triggered to detect that there are no users 21 on the trampoline 10. Moreover, the sensor 18 a can include passive infrared (PIR) sensors, ultrasonic (active) sensors, and microwave (active sensors) to operate as a motion detector.

Referring now to FIG. 4, a method 70 of operating the trampoline 10 is illustrated according to various embodiments. Assuming that the switch 36 is ON and users 21 are using the trampoline 10, the method 70 can begin in decision block 72, wherein it is determined whether there is any output from any of the sensors 18 a-18 h. The method 70 can loop until there is sensor output, whereupon in block 74, the output from multiple sensors 18 a-18 h is compared. In some embodiments, output from all of the sensors 18 a-18 h is compared. The remainder of the method 70 can depend on the comparison of the output of the sensors 18 a-18 h.

For instance, in block 76, it is determined if a user is within a predetermined distance, X, of the edge 22. X can be any suitable distance (e.g., 6 inches or less). Impacting the enclosure system 16 can also cause block 76 to be answered affirmatively. If block 76 is answered affirmatively, then block 82 follows, and light, sound, or other feedback signals are provided.

If block 76 is answered negatively, then block 78 follows, and it is determined whether the number of users is greater than or equal to a predetermined limit, Y. Y can be any suitable number. If block 78 is answered affirmatively, then, block 82 follows, and the feedback signals are provided.

If block 78 is answered negatively, then block 80 follows, and it is determined whether a predetermined movement is completed by the user 21. For instance, if output from the sensors 18 a-18 h indicates that the user 21 has completed a “lap” around the mat 14, then decision block 80 can be answered affirmatively, block 82 can follow, and feedback can be provided.

If block 80 is answered negatively, then the method 70 can loop back to the beginning. It will be appreciated that other the conditions of the users 21 described above or otherwise can be detected using the method 70 as well.

Thus, the feedback provided can enhance jumping activities on the trampoline 10 and/or provide warnings about the jumping activity, etc. Moreover, the system 20 can emit predetermined and preprogrammed patterned feedback. For instance, the speaker 40 can automatically count the number of jumps performed by the user. Various games can be conducted using the system 20 as well.

Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.

A trampoline comprising: a frame; a jumping mat assembly that is supported by the frame to allow at least one user to bounce thereon; an enclosure system that encloses at least a portion of the jumping mat assembly, the enclosure system including a vertical support that is coupled to the frame and that extends away from the frame, the enclosure system also including a flexible wall member that is supported by vertical support; a sensor system that includes a plurality of first sensors that are coupled to one of the frame and the jumping mat assembly to detect bouncing of the at least one user on the jumping mat, the plurality of first sensors being spaced apart from each other, the sensor system also including a second sensor that is fixed to one of the vertical support and the flexible wall member to detect impact of the at least one user with the enclosure system; a feedback system that provides a feedback signal; and a controller that compares output from the plurality of first sensors to determine a status of the at least one user, the controller operable to cause the feedback system to provide the feedback signal according to the determined status of the at least one user, the controller also operable to cause the feedback system to provide the feedback signal when the second sensor detects impact of the at least one user with the enclosure system.
 20. A method of providing feedback for at least one user of a trampoline comprising: generating signals from at least two sensors due to at least one user impacting a jumping mat assembly of the trampoline, the at least two sensors supported by the trampoline and spaced apart from each other; comparing the signals of the at least two sensors; detecting a status of the at least one user based on the comparison of the signals; and providing a feedback signal based on the detected status.
 21. The method of claim 20, wherein detecting the status includes at least one of: detecting a location of the at least one user relative to the jumping mat, detecting whether the at least one user has completed a predetermined movement relative to the jumping mat assembly, and detecting a number of the at least one user that are atop the jumping mat assembly.
